Here is a link to a channel on YouTube with interesting videos about all the different elements. You probably don’t have time to watch all of them (or maybe you do!), but choose a few from the PACE that you’d like to “see” or “explore” more and search for them on this channel: Periodic Videos
If you find other videos related to this PACE that you’d recommend, please put them in the comments below or use the contact form at the top of this page to send them to me and I will review and add them.
